Application January 5, masseria! No. 575 1 claim. (ci `azi-16) `Thisinvention relates to dispensing receptacles and, more particularly, to'receptacles'adapted to dispense their contentsin'an inverted positionand provided with a. self-closing outlet.

5 A` feature of one embodiment of the invention is that the closure mayreadily be adjusted to dispense liquids of different viscosity,'that is,if the closure is positioned to dispense free-flowing liquids, it mayreadily be adapted to emit more viscous liquids. y

A further feature is that the closure' is adapted to prevent liquiddroplets remaining on the closure valve when the receptacle is rightedsmearing and congealing on the outer surface of the closure device.

An object of the invention is to provide a simple. durable dispensingmedium that can be manufactured inexpensively and assembled readily.

Other features and advantages will appear in the following descriptionin conjunction with the drawings, in which- Figure 1 is a frontelevation of the improved dispensing receptacle; Fig. 2, a plan View;Fig. 3, an enlarged broken vertical sectional view; Fig. 4, a verticalsectional view of a modification; Fig. 5, a plan view of a lineremployed in the modification of Fig. 4; Fig. 6, a vertical sectionalview of another embodiment; Fig. 7, an elevation of a valve nipple; Fig.8, an elevationof a coil spring; and Fig. 9, an elevation of a liner.

Referring to the drawings, the reference character T designates areceptacle of any desired type adapted to contain a liquid to thedispensed. As here shown, it represents a small glass bottle adapted tocontain a lotion. The bottle 'l is provided with a neck 8 to which a capor top, constructed in accordance with my invention, is adapted to besecured. This neck may have a smooth surface so that the cap or top mayit frictionallythereon, but as shown in Fig. 3 at 9, it is preferablythreaded to receive a correspondingly threaded cap or top.

The cap I0, preferably fashioned from phenolic condensation material,comprises a Irusto-conical upper portion I I and a cylindrical lowerportion I2. The lower portion I2 is shown screwthreaded at I3 to coactwith the threaded neck 8 of the receptacle and has a vertical portion Ilextending above the threads. The frusto-conical portion I I terminatesina centrally located aperture adapted to receive tapered valve means I5.The upper edge I6 of the cap in Contact with the valve inclines slightlydownwardly and inwardly to form a groove for a purpose to be explained.The skirt I1 formed on the base of the valve I5 is adapted to bearagainst a shoulderll 8 in the inner part of` the `apex o the cap.Thebaseof the valve is also provided withanotch I 9 to house the uppersection of a coil spring 20 adapted to yieldingly hold the skirt of thevalve I1 against the 5 shoulder I8 of the cap. The lower convolution ofthe spring 20 rests on an annular centrally apertured washer or liner ZIdisposed on the top of the neck of thereceptacle. The spring 2B likewiseserves to yieldingly retain the washer 2| on l0 the bottle top to form aseal thereon when the receptacle is inverted.

It will be readily understood that to remove the liquid from thecontainer, the container is inverted and by the application of slightpres- 15 sure on the valve member I5, the valve will be unseated,permitting the ow of the liquid contents from the closure. The removalof pressure on the valve closes the cap and immediately halts the iiowof liquid. The provision of the 20 groove I6 on the edge of the closuretends to retain liquid dropletsremaining on the edge and to prevent itsilow along the outside of the closure.

It is also to be understood that the closure described may be adapted tocontrol the ilow 'of liquids of varying viscosities, that is, if thereceptacle contains a free ilowing perfume and it is desired tosubstitute a more viscous liquid, it is unnecessary to change the entireclosure device since by turning the cap one-half revolution in acounter-clockwise direction-or more, depending on the viscosity of theliquid and the pitch of the screw-threads, vthe tension onv the coilspring is lessened and the annular opening formed by unseating the valveis greater without a substantial increase in the pressure applied to thevalve. Conversely, the closure may be adapted for the admission of aless viscous liquid by turning the cap in aclockwise direction to form asmaller annular opening on the application of the same force.

A modified closure is shown in Figs. 4 and 5. In that embodiment thescrew-threaded cap 30, tapered .valve `22 and coil spring 23 are similar45 to those shown in Figs. 1-3 and 7-9. The lower coil of the springrests on a liner 24 pre!- erably fashioned from a phenolic condensationproduct and equippedwith threads 25 to engage they threads 26 on theinterior of the cap. The 50 liner is preferably provided on its uppersurface with an annular groove 21 adapted to receive the lowerconvolution of the coil spring and it may likewise be equipped withsuitable apertures 28 in which the prongs of a forked mem- 55 ber may beinserted to assist the insertion and removal of the liner. An annularthin cork or paper seal 29 may bedisposed between the liner and thebottle top to form the seal therebetween in shipping, it beingunderstood that the seal may be readily rupturedwhen the liquid is to beremoved. Y

A further modincation is shown in Fig. 6. In that modiilcation, thescrew-threaded cap I0, tapered valve 4|,Vcoil spring, and centrallyapertured liner 43 are similar to those previous- 1y described and shownin Figs. 1 to 3. The valve 4I, the coil spring 42 and the liner Il shownin Figs. 7, 8 and 9, respectively, are the same as the members describedin Figs. 1 to 5, and may be employed therein, except that the liner Ildiffers somewhat from the liner 24 of Figs. 4 and 5. The interior of theclosure cap 4I is provided with a centrally located depending ridge orwedge-shaped portion M. Upon assembling the closure, a portion of theliner 43 adjacent its periphery bears against the ridge portion M,spreading the periphery slightly to secure a tight nt in the closure anda seal above the hner.

While I have shown and described certain embodiments of my invention, itis to be understood that it is capable of many modications. Changes,therefore, in the construction and arrangement may be made withoutdeparting from the spirit and scope of the invention as disclosed in theappended claim, in which it is my intention to claim al1 noveltyinherent in my invention as broadly as permissible, in view of thevprior art.

What I claim as new and desire to secure by l0 Letters Patent is:

In an adjustable closure for dispensing receptacles, a hollowclosure-cap having a cylindrical portion terminating in a nozzle, aspringseat member movable vertically within the cyl5 lindrical portionof said cap, spring means dis- 'posed on said seat member, and a taperedmember protruding from said nozzle, normally closing the same by thepressure of said spring and forming an annular opening in said nozzlewhen 20 pressed inwardly, the size of the opening for a given inwardpressure depending on the position of the cap on the receptacle.
